I tried to reproduce using https://github.com/netlify-templates/gatsby-starter-netlify-cms and wasn't able to (either locally or on netlify).

Could you try to bump gatsby-plugin-netlify-cms to latest? I checked with version 4.1.40 and your version is 4.1.35 so that might have been fixed already?

If updating plugin doesn't fix anything, we will need reproduction repository for this

Nevermind. The error was with the version I guess. Tried 4.1.6 and it seems to work now.

Updating to gatsby@2.19.40 resolved this for me
